I’ve had my iPhone for about six months, and I’m always amazed by the wide range of apps available for it. From the flat-out silly, like “fart machine” to those much more useful like Tweetie and Fandango. It seems that no matter what your interest is, there’s an app for that.

I spent some time recently scouring the app store looking for tools that might be useful for those who want their sites to rank better on the search engines, for people interested in buying domain names, reviewing web statistics or monitoring the health of their web servers.

I was pleased at the number of applications available, many for free, some at reasonable prices, others – well – just a bit too high priced for me. The following lists are by no means all inclusive, and are not sorted in any particular fashion. They just happened to catch my eye somehow. You can (and should) click the app names for screen shots and more details about the app.

Search Engine Optimization iPhone Apps

Everyone wishes that their Web site(s) would get better placement on the search engines, everyone. Some of these might help, others – might get you banned.

Rankings
Cost: Free
What it does: enter a website address and a key word/phrase and the app will show you where the site ranks on Google, Yahoo & Live.

iSEO
Cost: Free
What it does: Enter web address and a search term and it tells you what page your result is on – but I have no idea what engine it checks. It also shows how many inlinks a web site has, but again – no idea where it gets the info.

WebFight
Cost: $.99 for full version, or Ad-supported lite version for free.
What it does: Enter two search phrases and it will tell you which has had more search traffic and provide snapshots of Google search for the phrase.

Pokeseo
Cost: $0.99
What it does: Enter a web address and the app shows you (occasionally) what the PageRank is and how many backlinks the site has from Google, Yahoo,Bing and AOL.

Whois
Cost: Free
What it does: Uses the Network Solutions whois to look for available domain names. Provides registration link if name is not taken.

Network/Server iPhone Apps

Every once in a while it’s just nice to reach out and ping someone, right? Well maybe not, but with these apps you can do that a few other network style geeky things.

iNetUtil
Cost: $0.99
What it does: Allows you to enter a list of sites you want to verify are “alive”, reports on the IP address and server software, provides whois information and displays the source code of the site.

Network Utility
Cost: $0.99 for full version, or ad supported free version
What it does: Allows you to ping a web site, scan its ports, perform GeoIP Lookup and whois queries.

Web Site Statistics

Without analytics, anything you do online (maybe anywhere) is just a moo point. If you want to know how your site is performing, these apps might just be what you need.

Analytics Agent
Cost: $2.99 for full version, or a ad supported “lite” version for free
What it does: Enter your Google account name it displays your Google analytics information for you.

Analytics App
Cost: $ 5.99
What it does: Provides access to every detail of your Google analytics data and reports.

Domain Tracker
Cost: Free
What it does: After you enter the domains you want to track, it provides you with the Google and Alexa page ranks. Allows you to track the history of the site.

In closing, it’s worth noting that many of the iPhone app developers have figured out the art of keyword stuffing. Hopefully Apple will figure this out soon and put a stop to it. As I browsed through the App Store it was clear from many of the title and descriptions that the developers were hoping to be found for words that don’t necessarily apply to their application. One of the SEO apps I considered reviewing, but decided to use the $4.99 elsewhere, had a 17+ rating and listed a huge list af reasons – including “Frequent/Intense Sexual Content or Nudity”. How disappointed must the people be that buy this app based on that disclaimer?

Do you have a favorite app that I missed? Love, or hate one of these? Let me know!
